Nitride Semiconductor LEDs

Abstract:  In this talk I will address issues related to epitaxial growth of Nitride Semiconductors and the applications of these materials to optoelectronic devices.  In particular I will discuss UV and blue-green LEDs, based on multiple quantum wells (MQWs) or quantum dots (QDs) of the AlGaN and the InGaN systems.  The physics and benefits of using textured QWs in LED structures based on these polar materials will be addressed.


Biography:  Theodore D. Moustakas has been a Professor of the Electrical and Computer Engineering Department at Boston University since 1987.  He has also been a Professor of Physics since 1991 and a Faculty Member of the Center for Photonics Research since 1994.  He received the B.S. degree in Physics from Aristotle University (Greece) in 1964 and the Ph.D. degree in Solid State Science and Engineering from Columbia University in 1974.  He held research and visiting faculty positions at Harvard University, Princeton University, Massachusetts Institute of Technology, Aristotle University, IBM T. J. Watson Research Laboratory and Exxon Corporate Research Laboratory.

Dr. Moustakas’ research contributions cover a broad spectrum of topics in opto-electronic materials and devices, including nitride semiconductors, amorphous semiconductors, III-V compounds, diamond thin films and metallic multi-layers.  He is the co-editor of eight books, including Gallium Nitride I (Academic Press, 1998) and Gallium Nitride II (Academic Press, 1999), the author of chapters in eight books and 250 papers in technical journals and conference proceedings.  He served as a special editor of the Journal of Vacuum Science and Technology in 1984 and 1986 and of the Journal of Electronic Materials in 1995.  He presented 93 invited and plenary talks in national and international conferences.  He has been granted more than twenty U.S. patents in the fields of nitride semiconductors, amorphous silicon and diamond materials.  Intellectual property that resulted from his work has been licensed to a number of companies, including the two major manufactures of blue LEDs and lasers (Cree in United States and Nichia in Japan).  This work is listed by the Association of University Technology Managers (AUTM) in their 2006 Edition of "Technology Transfer Works: 100 Cases from Research to Realization" (see
